In the present work, an integrated method of pole shape design optimization for reduction of torque pulsation components in permanent magnet synchronous motors is developed. A progressive design process is presented to find feasible optimal shapes. This method is applied on the pole shape optimization of two prototype permanent magnet synchronous motors, i.e., 4-poles/6-slots and 4-poles-12slots.

Accurate modeling of the wind energy conversion system is necessary to design and implementation of the control loop for the generator and the frequency converter, in order to extract maximum power from the wind and to investigate the effects of interconnection between wind farms and power system. In this paper the combination of a permanent magnet synchronous generator loaded with a diode rect...

In a hybrid energy system consisting of renewable sources of energy, there should be some storage facility or backup generation to maintain continuity of supply to the load when renewable source alone is not sufficient. The objective of this paper is to present one of such generating system that is capable of acting as a backup generator. This paper presents the modeling and simulation of a mic...

Renewable energy production plays a major role in satisfying electricity demand. Wind power conversion is one of the most popular renewable sources compared to other sources. has two types generators such as Permanent Magnet Synchronous Generator (PMSG) and Doubly Fed Induction (DFIG). The maximum tracking algorithm crucial controller, wind system for generating different speed conditions. In t...

The design of reliable controllers for wind energy conversion systems (WECSs) requires a dynamic model and accurate parameters the generator. In this paper, parameter measurement control direct-drive variable-speed WECS with permanent magnet synchronous generator (PMSG) are presented. An experimental method is developed measuring key PMSG. measured used in controllers. generator-side converter ...

Traditional permanent magnet synchronous generator (PMSG)-based wind turbine (WT) normally utilises phase lock loop (PLL) for obtaining accurate angle of AC grid to make sure maximum power point tracking (MPPT). However, a weak system with low short circuit ratio (SCR) and high control bandwidth PLL might have impaired effects on the stability system. To overcome these, novel PMSG-based WT form...

The recently stipulated grid codes require wind generators to re-initiate normal power production after voltage sag. This paper presents a comparative performance of two commonly employed variable speed turbines in today’s electricity market, the doubly fed induction generator (DFIG) and permanent magnet synchronous (PMSG) turbines. evaluation both was performed for weak, strong grids, consider...

ABSTRACT: The wind turbine generator is operated such that the rotor speed varies according to wind speed to adjust the duty cycle of power converter and maximizes wind energy conversion system efficiency. The rotating speed of permanent-magnet generator should be adjusted in the real time to capture maximum wind power. This paper proposes a quite simple maximum power point tracking control sch...

Wind is one of the most abundant renewable sources of energy in nature. Wind energy can be harnessed by a wind energy conversion system (WECS) composed of a wind turbine, an electric generator, a power electronic converter and the corresponding control system. The most advanced generator type is perhaps the permanent magnet synchronous generator (PMSG). As far as microgrid is concerned the load...
